Custom passive crossover


I recently purchased a pair of Altec 846A Valencia speakers. They are crossed over at 800-Hz.

My intention would be to build an improved dividing network using 12db Butterworth filters at 1.35 kHz to seamless blend the horn and woofer into one.

Unfortunately, I do not have the technical knowledge to design one. Impedance is 16 Ohms.

Does anyone have any advice?

With thanks,

Hi Horacio,

if you are reluctant to do it on your own given the wealth of information in this forum already written many times, get in contact with someone able to help you. Normally you would need a measurement gear with a microphone to observe how well your current crossover is doing.
